I agree with the posters wanting to see more of the young players, what's the point of not developing them? This team isn't going to make the playoffs.
However, as I and others have said repeatedly, none of the young players on this team are anything special, at all. They don't have a single player with star potential. Walker might become a notable player, but I'm only giving him the benefit of the doubt at the moment because we haven't seen enough of him to completely dismiss the possibility.
It certainly doesn't help that Pop built a weird team with stupid rotations, but I don't see any potential there.
